- Titanium is present in meteorites and the sun. Titanium, when pure, is a lustrous, white metal. It has a low density, good strength, is easily fabricated. The metal is the only element that burns in nitrogen. The metal combines with oxygen at red heat, and with chlorine at 550oC.
- Titanium is important as an alloying agent with aluminum, molybdenum, manganese, iron, and other metals. Alloys of titanium are principally used for aircraft and missiles where lightweight strength and ability to withstand extremes of temperature are important.
- An alloy is a substance composed of two or more metals, or of a metal or metals with a nonmetal, intimately mixed, as by fusion or electrode position.
- Titanium is as strong as steel, but 45% lighter. It is 60% heavier than aluminum, but twice as strong.
- The metal has excellent resistance to sea water and is used for parts of ships exposed to salt water
- Titanium dioxide is used for both house paint and artist's paint, because it is permanent and has good covering power.
- Titanium paint is an excellent reflector of infrared, and is used in solar observatories where heat causes poor viewing conditions.
